WINDOW STRUCTURE.

Application led April 12, 1926. Serial No. 101,669..v

My invention' relates, more particularly,

to window structures ofthe type comprising vertically movable upper .andlower sashes which are offset one from the other to of each being movedthroughout vthe eight of the window frame.

My primary objects are to provide a construction of window structurewhereb the window sashes may be so manipulate ythat both sides of thewindow panes therein may be rendered readily accessible, more partic-lularly, for washing from the inside 'of the o o l U window; to provideimprovements in wm- `dow structures of the type above referred to, andmore particularly of the typewherein the window sashes are "pivotallymounted in frames which slide u and down in the window frame, to the enthat the same, or substantially the same, transparent areas lpresentedby window structures of the common type, w1ll be presented in window.structures embodying myimprovements; to provide improvements in windowstructures of the eneral characterabove stated and resenting thefeatures above referred to, to the end that window structures of thetype referred to and as commonly provided, namely,.of such constructionthat the window sashes have no movement in the window frame other thanan up and down movement, may be readilyv and economically rel 4vmodeledto embody my improvements, without reduction'of the transparent areasofthe window structure. v

Referring to lthe accompanying drawmUs:-

Figure 1 is a face view of a window structure embodying my improvements,viewing the structure from the inside of the room. Figure 2 is .avertical sectional view taken at the line 2-,-2 on Fig. 1 and viewed inthe direction of the arrows. Fi ure 3 is a plan sectional view taken atthe lme 3-3 on Fig. 1 and viewed in the direction of the arrows, thisview showing by full lines the lower, inner, sash in lowermost closedposition, and by dotted lines one of the positions occupied by thislower sash when swung inwardly, and the position occupied by theremovable sash stop cooperating therewith to permit this sash to beswung inwardly. Figure 4 is an enlarged broken view taken at the line 4on Fig. 3 and viewed in the direction of the arrow; and Figure 5, aperspective view of the u per sash and the -frame in which it is pivotay mounted.

ermit Referring to the articular construction shown, the window frame isrepresented at 6, the opposite lateral side walls 7 and 8 of which,contain vertical grooves 9 and 10, and 11 and 12, respectively,extending sub- \stant1ally the full height of the window opening, thegrooves 1() and 12 being located .toward the outer side of the frame 6and in parallel spaced relation to the grooves 9 and 12, respectively.

Slidable up and down in the grooves 9 and 11, is a frame 13 of generalrectangular form and preferably formed of metalv adapting the sidemembers 14 and 15 thereof and the top and bottom members 16 and 17thereof, to be made relatively thin and still resent the desiredstrength. The side mem ers 14 and 15 are shown as provided adjacenttheir lupper and lower ends with lugs 18 and 19, and 20 and 21,respectively, at which this frame extends into the grooves 9 and 11 andby means of the side walls of which latter this frame is guided in itsup and down movements, the upper lugs 18 and 2O servino as means forattachment thereto of the usual window sash cords for counterbalancingthe weight of this window section. V The frame 13 is equipped with awindow sash proper 22 which may be, and preferably is, formed of woodand is of a shape and size to fairly snugly fit within the openingprovided by the frame 13. The-sash 22, which is equipped with a pane 23of glass, is pivotally connected with the frame 13 to swing on avertical axis, and to this end the sash 22 is rovd'ed, adjacent onelateral edge thereo namely, the right-hand edge in Figs. 1, 3 and 5,with lugs 24 and 25 containing vertically disposed openings therethroughand into which ldownwardly andv upwardly projecting pivoting pins 26 and27 carried by lugs 28 and 29 provided on the top and bottom members 16and 17 of the frame 13, extend, thereby permitting the sash 22 to beswung on the pivots thus provided into and out of the full line positionshown in Fig. 3.

The window frame 6 at the edge thereof adjacent the pivots 26 and 27, isprovided with a cleat 30 so positioned as to overlap `and form a tightjoint between it and the adjacent vertical side member of the sash 22when this sash is in the closed position shown by the full lines in Fig.3, it being intended that this cleat be permanently secured in place.The window frame 6 at its los - section of the window.

opposite side is provided with a vertical cleat formed of an uppersection 31 permanently secured to the window frame and a lower section32 in vertical alignment with the section 31, but removably7 secured 1nplace, as for example by hinging it to the window frame, as representedat 33. The cleat formed of the sections 31 and 32 cooperates with theadjacent edge portion of the sash 22 in the way describedof the cleat30, the cleat section 32 extending slightly above the upper edge of thefr ame 13 when the latter is in lowermost positlon, as shown in Fig. 1.

Slidable up and down in the vertical grooves 10 and 12, is a frame 34 ofthe same construction as the frame 13, this frame being guided in thegrooves 10 and 11 by lugs at its lateral sides as explained of the frame13, the lower lugs of the frame 34 being represented at 35, it beingunderstood that the upper lugs thereof, (not shown), would be connectedwith the sash-weight-cord lfor cooperation with the upper, outer slidingThe frame 34 contains a sash 36`pivotally mounted therein as explainedof the sash 22, the upper pivot of this outer sash beingrepresented at37, and its pane of glass at 38. The window frame 6 is provided, betweenthe vertical planes in which the respective window sections are movable,with parting strips 39 and 40. The parting strip 39 which extends thefull height of the window opening, may be provided as a single sectionand permanently secured to the window frame. The parting strip 40 isformed of two vertically aligned strip sections 41 and 42, the loweredge of the section 41 extending above the upper edge of the frame 34when the latter is lowered in the window frame to its lowermostposition. The strip section 41 may be permanently secured to the windowframe, if desired, whereas the strip 42 is provided as a removablesection, and to this end it is preferably provided with a plate, or thelike, 43, which depends below the lower edge of the strip 42 and isadapted to extend into a slot 44 in the bottom cross member of thewindow frame, the u per end of the section 42 preferably exten ing intoa recess 45 provided between plates 46 secured to the lower end portionof the section 41 at opposite sides thereof.

The parting strips 39 and 40 are preferablv of such dimensions as toprovide a close sliding fit between them and the window sashes. Thewindow frame 6 at its front strip portions 47 and 48 overlaps the frontsurfaces of the vertical side members of the saslli136 and forms a closesliding fit therewit l It will be understood from the foregoing that thesashes 22 and 36 slide up and down in grooves provided at opposite sidesof the window frame 6 and with the walls of which the sashes haverelatively tight sliding fit thereby renderin the window structuresubstantially air tig t.

It will further .be understood that the sectional parting strip 40 andthe cleat formed of the vertically aligned sections 31 and 32 form stopspreventing the window sashes 22 and 36 from swinging inwardly, in thenormal condition of the window structure, but by reason of theirdisplaceable sections 32 and 42 permitting of such inward swinging ofthe sash as and for the purpose hereinafter described.

Assuming that it is desired both sashes 22 and 36 be swung inwardly onthe frames 13 and 34 in which they are carried, as for example to permitof the ready cleaning of both sides of the window panes of the twosashes by a person standing on the floor, the operator, assuming theinside frame 13 Vto be in normal, lowered, position, swings the cleatsections 32 outwardly to the dotted position shown in Fig. 3, theoperator first turning the turn button 31u to release the section 32,and thereupon swings the sash 22 inwardly as for example to the positionshown by dotted lines in Fig. 3. The operator then raises the frame 13and sash 22 to the top of the window frame and lowers the frame 34 andsash 36 to the bottom of the window frame whereupon, upon removing thclower parting stripsection 42, the outer sash 36 may be swun inwardly asin the case of the inner sash as above stated.

It will be understood from the foregoing description that the windowstructure, according to applicants invention, may be comparativelysimple and inexpensive, per mitting of the ready mani ulation of thesashes upon thc respective rames in which they are carried, tofacilitate cleaning and repairs, and all without sacrifice of the areaof transparent surfaces provided by the windows. Furthermore,particularly in vicw of the fact that the relatively thin frames 13 and34 are provided, window structures of the form as commonly provided maybe readily remodeled at comparatively little expense to present myimprovements and without sacrlfice of transparent area.

While I have illustrated and described a particular constructionembodying my invention, I do not wish to be understood as intending tolimit it thereto as the same may be variously modified and alteredwithout departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is:
